GARBID-GARTRID GE Specification of Letters Patent.

Patented Feb. 25, 1908.

Original application filed March 9. 1907- Serial No. 361.562. Divided and this application filed August 6. 1907- Serial No. 8871279- To all whom it may concern:

. Be it known that I, EDWIN M. RosEN- BLUTH, of Philadelphia, in the State of Pennsylvania, have invented a certainnew and useful Improvement in Carbid-Cartridges, whereof the following is a specification, reference being had to the accompanying drawings.

This application is a division of my ap plication for improvement in acetylene gas generators, Serial #361,562, filed March 9th, 1907; and relates specifically to receptacles which contain the carbid and which are removably carried by the generator.

My invention provides a carbid receptacle arranged to contain both carbid and ashes,

with means to evenly distribute a flow of water to said carbid, and aims to prevent the improper insertion of said receptacle into the carbid chamber of a gas generator. casing, and further provides a screen arranged to support the undecomposed carbid whereby the loose particles of ashes may be conveniently sifted therefrom.

My invention also provides means whereby the original canister, in which the supply of carbid is carried, may be inserted as a carbid cartridge within said carbid receptacle, and means whereby said canister may be substituted for said carbid receptacle.

Although the carbid may be loosely placed, in the carbid receptacle, and therein. decomposed, such receptacle may be made of such dimensions as to inclose the original canister or cartridge containing the carbid, so that by simply removing the lid which incloses the carbid in said cartridge and inserting said cartridge into the carbid receptacle, gas may be generated by decomposing the carbid in said cartridge, and when all of the carbid contained therein is reduced to ashes, said cartridge may be removed from said receptacle and discarded so that the necessity of cleaning the receptacle is avoided.

The form of my invention hereinafter described comprises a carbid receptacle having one end enlarged and provided with an imperforate cap for said enlarged end, a perforated cap for its smaller end having intersecting grooves arranged to direct water to said perforations; a removable screen ar ranged to fit within said enlarged end, and grooves extending around the wall of said receptacle arranged to retain the ashes.

My invention also comprises a carbid canister arranged to be used as a carbid cartridge, having an opening in its top covered by the cap of said carbid receptacle and provided with indentations at intervals in its upper periphery to permit the free escape of gas therefrom.

My invention also includes the various novel features of construction and arrangement as hereinafter more definitely specified.

In the accompanying drawings Figure I, is a central vertical longitudinal view of a generator conveniently embodying my improvement. Fig. II, is a side elevation of the removable carbid receptacle. Fig. III, is a central vertical sectional view of said carbld receptacle taken on the line III, III, in Fig. II. Fig. IV, is plan view of said carbid receptacle. Fig. V, is a central vertical sectional view of the carbid canister. Fig. VI, is a plan view of said canister. Fig. VII, is a central vertical sectional view of said canister shown as a cartridge; the perforated cap of the carbid receptacle being substituted for its original imperforate lid. Fig. VIII, is a plan view of said perforated cap.

Referring to Fig. I; the generator is rotatably supported in the bracket 1, which is provided with the alined bearings 3, and 4, for the alined trunnions 5, and 6, on the generator casing 7, and said bearings respectively comprise clamping yokes 9, and 10, arranged to retain said trunnions.

As shown in Fig. I the generator casing 7, comprises the upper and lower walls12, and 13, having the circular openings 14,.and 15, respectively surrounded by the flanges 17, and 18 the flange 17, being fitted to the gasket 20, in the removable lid 21, and the flange 18, being provided with the gasket 22, to which the movable lid 23, is fitted. Said opening 15, is sealed by the cup shaped casing 25, having its open end terminating in the annular flange 26, which is secured to the wall 13, to form the gas tight carbid chamber 28. The closed end wall 29, of said casing 25, extends close to the wall 12, of the casing 7, and is secured to the flange 17, by the annular rim30, having the apertures 31, for the passage of the water 33, into the inclosure formed by the lid 21. Said closed wall 29, is provided with the valve. 35, which is conveniently disposed in concentric relation with the opening 14, and comprises a reciprocatory plunger stem 36, arranged to restrict the passage of water from said inclosure through said valve, and to clean the-passageway 37, when clogged.

The removable carbid receptacle 40, is arranged to snugly fit within the cup shaped casing 25, and comprises the cylindrical shell 41, having one end enlarged at 42, to prevent its being improperly inserted in said casing 25. Said large end is fitted with an imperforate cap 43, having diametrically opposite bayonet slots 45, (similar to that shown at the bottom of Fig. II, and hereinafter described) arranged to engage the lugs 46, projecting from the enlarged portion 42, of the shell 41. The small end of said receptacle 40, is fitted with the perforated cap 48, as shown in plan in Fig. VIII, comprises the annular rim 49, and the central disk 50, connected with said rim by the radial bars 51. Said disk 50, is provided with the central recess 52, having the aperture 53, which is covered by the inwardly extending conical dome 54, arranged to receive the plunger 36, when the carbid receptacle is inserted inthe generator as shown in Fig. I. The series of radial grooves 55, connect the recess 52, with the arc openings 57, and, the circular groove 60, intersects said radial grooves 55, and connects them with the radial slots 61, so as to uniformly distribute the water supplied thereto through the central inlet.

As shown in Fig: I, the carbid receptacle 40, is pressed into the chamber 25, by the coiled spring 65, in the lid 23, to inclose the removable carbid cartridge 67, which is similar to the canister shown in Fig. V, and. hereinafter described. Said cartridge 67, con tains both loose carbid 68, and the carbid ash 69, but retains the latter at one end of the cartridge shell, so that the carbid 68, may be supported remote from the ash 69, as shown in Fig. I, or be held in contact therewith by gravitation, in accordance with the position of the generator, which latter may be conveniently inverted by the handle 7 O, on the casing 7.

In the form of my invention shown in Figs. II, III and IV, the carbid receptacle may directly contain both the carbid 72, and the carbid ash 73, as shown in Fig. III. Said receptacle comprises the cylindrical shell 75, having the enlarged end 76, provided with the imperforate cap 77, having the bayonet slot 78, engaged with the studs 79, as best shown in Fig. II. The small end of said receptacle 7 5, is provided with the perforated cap 80, having the bayonet slots 81, arranged to engage the studs 82. Said shell 75, is provided with the corrugations 85, adjacent to its small end, arranged to detain the ashes 73, and, its large end is provided with the removable carbid supporting screen 87, which may be conveniently manipulated by the handles 88, extending from its opposite surfaces. Said screen 87, is reversible and comprises the annular rim 89, arranged to maintain it in such relation to the cap 7 7 as to provide space for such ashes as may be sifted from the carbid through said screen into said imperforate cap 7 7.

As best shown in Fig. IV; the cap 80, is provided with the central recess 92, having the opening 93, in concentric relation therewith, and covered with the inwardly extending conical dome 94, the series of circumferential openings 95, is connected with said central opening 93, by the radial grooves 96, intersected by the concentric circumferential grooves 97, and 98, leading to the radial apertures 99, to insure the even distribution of water to the carbid contained in the receptacle.

It may be noted that the canister 100, as shown in Figs. V and VI, when hermetically sealed by the removable lid 101, serves to store and transport carbid, but may be conveniently utilized as a carbid cartridge, or, may be substituted for the carbid receptacle above described, when said lid 101, is removed and the perforated cap 48, of the carbid receptacle, substituted therefor as shown in Fig. VII. As shown in Figs. V, VI and VII, said canister is provided with notches 102, in its upper periphery to facilitate the escape of gas therefrom.

I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention, as defined in the appended claims.
